Stainless Steel 321H Pipes are a high-carbon variant of the titanium-stabilized 321 grade, with enhanced high-temperature strength and creep resistance. The alloy generally consists of 17–19% chromium, 9–12% nickel, and stabilization with titanium, with increased carbon content up to 0.10% to have enhanced performance in high-temperature conditions. These pipes have tensile strength of 515–750 MPa and yield strength of approximately 205 MPa. Stainless Steel 321H has good oxidation resistance up to 900°C and excellent weldability and resistance to thermal cycling conditions.

Why Choose Stainless Steel 321H Pipes from Blundell Pipes and Tubes?

Stainless Steel 321H pipes are made from a titanium-stabilized austenitic chromium-nickel alloy that has a higher carbon content than 321, which boosts their high-temperature strength. Typically, they contain 17–19% chromium, 9–12% nickel, and 0.5% titanium. These pipes boast impressive mechanical properties, with a tensile strength ranging from 515–750 MPa, yield strength from 205–275 MPa, and elongation between 35–45%. They are highly resistant to intergranular corrosion, oxidation, and thermal creep, making them ideal for continuous use at elevated temperatures.
